To (11/ whom Ill/(by concern:

Be it known that I, CARL W 'nnuu, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Circularall Constructions for Chimneys, Bins, Cisterns, and the Like, of which the following is a specification.

The object of my invention is to erect the walls of large chimneys, tanks, storage-bins, cisterns, and other large circular structures of a composite construction of hollow building-blocks of baked clay, a cement mortar, concrete, or any suitable variety of natural or artificial stone, and metal-reinforced concrete to the end of attaining in such structures the combined advantages of brick or block and concrete constructions and to that end to render them solid and monolithic in character.

To carry out my invention to the best ad vantage, Iemploy a particular form of hollow block in the manner illustrated in the accom panying drawings, in which- Figure l is a partly-sectional plan view of a wall constructed according to my improvement; Fig. 2, a perspective view, diagrammatic in its nature, showing the manner of disposing the blocks; and Fig. 3, a perspective view of one of the blocks.

A is a hollow block of any of the materials referred to, of the variety technically known as a hollow radial block. It is arc-shaped on its outer and inner surfaces and comprises in the form represented a solid section a of about one-half its length, flat on top and bottom, with a recess (1* in one rectangular end and with ribs (1 and a extending from its opposite end, forming continuations of the arc-shaped outer and inner surfaces and the intermediate space a, which render the block hollow. The general shape of the block may be varied, however, and the sizes thereof employed may be any that are required, though all the blocks used in a wall should be of the same shape and size.

To erect a wall B with the blocks A, the first circular course thereof is, as represented in Fig. 2, laid on a suitable foundation (not shown) with the ribs (1 and (1 all extending in the same direction. The blocks of the second course are laid upon those of the course below in break-joint arrangement by simply turning them over lengthwise or reversing them to extend contrarily to those first laid and bringing their spaces a coincident with those of the respective blocks in the first course. The third course is formed by laying the blocks as in the first course, as shown of the upper blocks in Fig 2, with their lines of junction alining with those of the blocks in the lowermost course, and this plan of disposing the blocks is observed throughout the entire circular structure, causing the spaces r1, with the recesses u (if employed, though they are not iiulispensable) to form a circular series of vertical wells extending through the wall from top to'bottom. As the laying of the blocks progresses and the resultant wells are being formed metal bars 1), preferably of the T variety (reprcscntial in Fig. 1) or cables, are placed in vertical position and in desired number in the wells and concrete or mortar is filled in about them and also about similar circumferential bars (1, if used, as they ordinarily are, being provided to intersect the vertical bars at suitable intervals-say one at each course of the blocks which are provided in their solid sections 1/ with grooves (1 coincident on the top and bottom of each block to admit the bars (a The vertical bars take up the bonding forces to which the wall is subjected from windpressure and other causes, and the filling of mortar or cement embedding the reinforcingbars besides preventing them from rusting by shielding them against oxidation renders the entire wall construction solid and monolithic in character and capable of withstanding high crushing forces.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. A wall construction comprising, in combination, blocks laid in superimposed courses, each block being provided with a recess at one end, said blocks being laid in break-joint relation and in reverse order in alternate courses to bring the vertically-successive re cesses into alinement and form vertical wells, metal reinforcing-bars disposed vertically in said wells, and concrete or thelikc embedding said bars in the wells.

2. A wall construction comprising superimposed courscs of blocks, said blocks being recessed at their ends and laid in break-joint relation and in reverse order in alternate courses thereby forming vertical wells in the wall structure, reinforcing elements extending vertically through said wells, and concrete or the like filling the wells to embed said elements and bind the blocks laterally.

3. A circular-wall construction comprising, in combination, hollow blocks of the character described, having solid grooved portions with ribs extending from one end of each said solid portion forming a space between them, said blocks being laid in courses with their spaces in vertical alinernent forming a circumferential series of vertical wells, metal reinforcing-bars disposed vertically in said wells, circumferential metal reinforcing-bars confined in the grooves in said blocks between courses thereof and intersecting said vertical bars, and a filling of concrete, or the like, in said wells, embedding said bars therein.

4. A circular-wall construction comprising, in combination, hollow blocks of the character described, each having a solid grooved portion with ribs extending from one end forming a space between them and continuations of the inner and outer surfaces of said solid portion, said blocks being laid in courses with those in each course disposed in break- CARL WVEBER.
